MACHINE FOR JUSTIFYl NG TYPE.

SPECIFICATION forming part of Letters PatentNo. 700,712, dated May 20, 1902. Application filed June 29,1901. Serial No. 66,520. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN WATSON, a citizen of the United States, and a resident of Brooklyn, Kings county, State of New York, have invented certain new and useful Improvementsin Machines for Justifying Type, of which the following is a specification.

My invention'relates to an improvement in the rock-shaft and trip-lever mechanism of type-justifying machines of the class shown and described in application No. 24,291, filed able seat cut in the inner face of the drum 350, as shown, and the spring 354 tends to hold July 20, 1901, which is the invention of Frank McOlintock, and refers particularly to a device whereby the rock-shaft trip-lever mechanism whichreleases the clutch, and thereby locks the justifying mechanism temporarily to the constantly-rotating j ustifier-shaft, will be positively withheld from being retracted after the withdrawal of each space-bar in a line, as has been the case heretofore in machines of this class. This has been foundin practice to require a line-holder of considerable weight or the use ofsuitable driving mechanism to insure that the momentum of the line-holder shall be sufficient at all times to actuate the rock-shaft and trip-levers, and thereby prevent a stoppage of the j ustifier mechanism before the completion of the justifying and spacing of the entire line.

The invention may be understood by reference to the drawings, in which- Figure 1 is a front elevation of the machine with the parts in the position they assume just before the justifying mechanism is caused to operate by the advancing lineholder, and Fig. 2 represents a plan view of a portion of the driving-shaft with sleeve and rollers attached.

In the drawings, w is the justifier-shaft, which constantly rotates.

0 is a sleeve carrying the cam 339 and the other devices connected thereto shown in the application referred to.

337 is a roller carried upon the justifierslide 338.

341 is the rock-shaft,arranged to rotate on the bearing 342 on abracket 343, attached to the bed-plate and at the other end in a hearing in .theplate 344, attached-to the sideplate .f, andwhich performs various other functions.

The rock-shaft 341 terminates at its outer end ,riphery. an annular drum or. disk 350, which by means in a bent'arm 345, the lower extremity of which is provided with a projection 346. The shaft 10 carries, as shown, a disk 348, which is secured to and rotates with it in the direction shown by the arrow, which disk is provided witha series of cog-teeth 349 on its pe- Surrounding the cog-wheel 348 is of a long sleeve 0 carries cams necessary to the mechanism, among them the cam 339.

' 352 is a toothed dog pivoted at 353 in a suitthe tooth of the dog normally in engagement with some one of the cog-teeth 349 on the cogwheel 34S. The outer end 346 of the arm 345 rests normally when the justifying mechanism is not in operation under the lever 347, thereby compressing the spring 354 and holding the dog back from the teeth until such time'as the arm 345' is moved by appropriate mechanism. In order to move the rod.345 at the right instant, the hanging rod 355 is provided at the inner end of the rod 341, which descends intd a recess in the side plate f. 'This recess contains a slide 356, which projects out into the slot in the line of travel of the thin end of the space-bars, as shown 'in the aforesaid application, and this slide is held in its normal position by means of the spring 359 until such time as the extremity of the foremost space-bar in the line holder 0 comes in contact with and forces in the slide, thereby compressing the spring 359 and causing the rod 355 to swing forward, thus rotating the rock-shaft 341 and releas ingthelever 346, and thereby the dog 352. The dog thereupon immediately engages with one of the teeth of the cog-wheel 345 and the disk 350, and the disk 350 is rotated, carrying with it the cam 339. In the operation of the ma= chine the space-bar is thereupon immediately withdrawn from the line-holder in order that a space-blank may be inserted in lieu thereof in the manner described in the application referred to. The withdrawal of the space-bar allows the slide 356 to be returned to its nor mal position by means of the spring:359, thus returning the rock-shaft attend the bent lever 345 to its normal position,with the end 346 of the said lever in contact with the face of the drum 350. In the machine described in said application it is necessary that the succeeding space-bar shall again move the block 356 and compress the spring 359 and rotate the rock-shaft 341. In order that the rockshaft 341 and the levers 345 and 355 may be maintained in their outward position after the first space-bar in the line has actuated them and prevented from being retracted by the spring 359 during the entire justification of each line, a cam-ring 360 is provided upon the outer face of the drum 350, which is of such thickness that the rock-shaft arm 346 is held in its outward position during that portion of the revolution of the drum 350 covered by the cam-ring 360. Before the end of the cam-ring 360 has cleared the arm 346 the line-holder will have moved forward sufficiently to bring the point of another space-bar in contact with the slide 356, and thereby prevent the retraction of the slide 356 and the rock-shaft and levers until such time as the cam-ring 360 has again engaged the arm 346. The engagement between the dog and the arm 346 is thus prevented until after the entire operation of removing the space-bars and inserting spaces has been completed for each line in the lineholder. I

I claim as my invention- 1. The combination of a rotating shaft driven from a suitable source of power; a cogwheel on said shaft; an annular ring running loosely on said shaft, surrounding said co wheel; a pivoted dog controlled by a spring in the periphery of the ring, arranged to engage with the cog-wheel; a cam upon the shaft, engaging with a block upon the bar, arranged to hold the bar normallyout of operation except when the block is moved off of the cam by the rotation of the shaft; mechanism, substantially as described, actuated by the foremost space-bar in the line-holder, for throwing the dog in and out of engagement at the proper instant; and means for preventing the mechanism from resuming its normal position while each space-bar is being withdrawn from the line-holder.

2. The combination of a rotating shaft driven from a suitable source of power; a 00,,- wheel on said shaft; an annular ring running loosely on said shaft, surrounding said cogwheel; a pivoted dog controlled by a spring in the periphery of the ring, arranged to engage with the cog-wheel; a cam upon the shaft,

engaging with a block upon the bar, arranged to hold the bar normally out of operation eX- cept when the block is moved off of the cam by the rotation of the shaft;mechanism, substantially as described, actuated by the foremost space-bar in the line-holder, for throwing the dog in and out of engagement at the proper instant, and a cam-ring of suitable length, attached to the face of the cam along its periphery, for holding the end of the bent lever out of engagement with the connecting mechanism during a complete revolution of the cam.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 28th day of June, 1901.
